Redirect a site with or without www

If you want all visits to your site to always use the version with www (or without it), you must edit the *.htaccess file located in the public_html* root folder.

To force your site URL to use WWW, add:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^dominio.com [NC]
RewriteRule ^(.*)$ http://www.dominio.com/$1 [L,R=301,NC]

To force your URL to use no WWW, add:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^www.dominio.com [NC]
RewriteRule ^(.*)$ http://dominio.com/$1 [L,R=301]

IMPORTANT NOTE: remember to replace "dominio.com" (both in line two and line three of each case) with your website's actual URL.
